Maps freezing

Interesting Warren

Have you tried a 3.1 amp usb. Reckon a 2.1 amp is tad small with a tablet working.

I assume you now set the app to stay awake.

Hi Trevor, Afaik the highest individual output for usb 2 is 2.1 A, unless the device is one of the quick charge devices? I've actually got the Jaycar high power usb 4x outlets, 2x2.1 A + 2x1 A, total 6.2 A. I wonder if that output is achieved, as when I connect a power bank it seems to increase the charge rate?

Both Jaycar & RTM sell 2.4A USB outlets. They certainly make a difference to power hungry tablets/iPads.

I recently bought a couple of USB outlets from China. Both have twin 2.4A outlets, but it was a long wait!

They are available Warren, sorry, cant remember where i got mine.

As Bob has suggested even a 2.4a might help a bit

Thanks Guys, will have a more forensic look at the Jaycar catalogue, maybe download the pdf copy. Online searches can sometimes be a problem if you don't crack the exact keyword, some are better with cross referencing than others. Otherwise the long wait for supply from China.

Checking the device I have the Jaycar 7.2A 4 PORT USB CAR CIGARETTE LIGHTER ADAPTOR
MP3686 Current Output 2.4A (Each Port Max), 1.8A (Across all Ports), 7.2A (Total)
The quickcharge adaptors descriptions in the catalogue state they default to 2.4A max if not a quickcharge device.
I will check what settings I have enabled as per Michelle's post. I certainly have the stay awake feature enabled. My assumption always has been that it was an issue with the cheap device.

EOTraveller/EOTopo is the only thing running on the tablet and is always on, never allowed to sleep.

It seems to happen most often when the vehicle has been stationary, then I move off. I come to the next track intersection or geographical feature and look at the map and my position hasn’t moved. Hit the home button at the top, then return to the map and the snail trail straight lines to current position and stays like that.
Other times I will be driving looking for a turn or feature and not realise the map has frozen and I go past thinking I’m not there yet, stop and do the above procedure to find I’ve missed my turn or feature.

I’m using the app with GPS only, as there is never any mobile service in the areas I’m poking around in, Vic high country and surrounds mostly.

Cheers

HI Daryl,

It sounds like your device is running out of RAM or you have a setting in the device which is switching off your GPS (eg. a security/anti-virus app or something similar), or the Battery Saving feature in the Android operating system is turning off the GPS - all these things can and do happen to people out of the blue so please carefully check your device for these sorts of issues.

With RAM - this issue could occur if you aren't regularly closing your apps (ie. overnight) and then giving the app a chance to reboot (clears out cache and refreshes RAM) when you launch it the next day.
So check that you are not just mistakenly pushing the app to the background instead of correctly closing the app.

(ie. using the back button to shut down the app only disables it and pushes it to the background but doesn't' actually close it. ). The exact method to close an Android app varies from device to device and is dependent on the version of the Android operating system you have - up until Android 10, you would tap the left softkey and then press Close all apps, or just select one app to close by swiping it away.

I'm also interested to know which version of the Android operating system is running on your device? In our experience the really strange issues like this that don't make much sense, only seem to occur on devices that are running very old versions of the operating system, ie. be aware that once Android stops supporting a version, you no longer get the bug fixes and security updates and that can mean all manner of things can upset your system and makes it impossible for us to know how to troubleshoot. Can you get an update for the Android operating system on this device?
